Product Description

The Injen SP1391P Polished SP Short Ram Intake is a high-performance aftermarket intake system designed specifically for the 2010-2012 Hyundai Genesis Coupe equipped with the V6 3.8 L engine. Part of Injen's flagship SP Series, this intake replaces the restrictive stock air path with mandrel-bent 6061-T6 aluminum tubing and incorporates patented MegaRam (MR) and Air Fusion technologies to optimize airflow while maintaining safe air-fuel ratios without requiring ECU retuning. The included SuperNano-Web dry air filter offers increased surface area for airflow and filtration, and the custom heat shield helps isolate warmer engine bay air to improve intake efficiency.

Dyno testing shows measurable gains of up to approximately 10 hp and 9 lb-ft of torque compared to the factory intake, translating to stronger throttle response and enhanced acceleration for spirited driving. Finished in polished aluminum for a premium appearance under the hood, this intake also produces a more aggressive induction sound during acceleration. Backed by Injen's limited lifetime warranty, the SP1391P delivers a reliable, direct-bolt-on performance upgrade for Genesis Coupe enthusiasts. Note that this intake is not CARB exempt and may be restricted in states with strict emissions regulations.
